LISTEN TO HIM GUYS... No Truer statement can be made about this issue ! Also, because the programming code is tightly held by MB and they only provide "basic maintenance tuning maps" to their aftermarket technicians. Also, because the OEM ECU software updates / changes often require two way communication with "big brothers's computers" it is very difficult to manilpulate the codes... I'm not saying it can't be done, because I know a programmer (Bosch ECU Tech) here in LA that can do it, but he charges $400 per hour and estimates that such a project would require multiple hours and multiple dyno runs with AFR logging... (appx. $2,500 worth of work) and he will not guarantee satisfactory results...

That is why I have scrapped my OEM ECU on the race car for the SRT6 engine swap and went with a MOTEC M600 system... It might be a little pricey ($4,500) without tuning, but it has the capability of handling any future modification I might put into the engine (eg. swapping the SC for TC, etc.)

 

I agree with both
This is the same problem that the srt-8 guys have. It's very hard to break the codes in these PCM's. Chrysler, and Diamler work VERY hard to keep their programing a secret.
And the stock PCM will compensate 33% rich or lean from initial programing.

 

don't worry guys, it will be figured out sooner or later, just be patient.

 

LOL... OK MAX... Why don't you read and comprehend the posts that you respond to ? It already is figured out... But the costs are extreme compared to other OEM systems...

HELLO KNOCK KNOCK, ANYONE HOME IN THERE ?

 

Look man, I know a boosted NA Crossfire is possible and right now it cost about $6-$8k to do.

Right now everything is hinging on the V8 swap, If LantanaTX can prove successful in unlocking and re-code the V8 ecu to his crossfire, we NA guys can easily buy an SRT6 ecu and do the same. this will bring the cost down to about $3500 for a home made system!

so like I said we just have to sit tight!

 

There are more to Lantana's engineering problems than just the ECU... I hope he has the time and $ to rectify them... I'm rooting him on !!! It's a VERY unique project and would be a wonderful challenge to tackle....

 

Come on derek, Maxwell knows way more about this car than you do. Im sure he has invested three years and countless dollars and just trying to understand how to make his crossfire faster like you have, found a bosch engineer to discuss the issues with and finish second in his class at nasa. I mean, if he hadn't, then why would he be spewing so much crap all the time, right?

 

sounds like dribble to me. Go back to your MAzda 3 forum.

 

Sorry its been so long guys....been crazy busy lately. I will try to be on as much as I can to update everyone that is interested in turbocharging their cars...heres a sneak peak.....if you need any more info please feel free to write me at rico_valverde@hotmail.com

 

You put the turbo on the wrong end of the car!

 

Even WITH the MB computer, breakout box, and Star software........it's EXTREMELY hard to change anything in the ECU.

 

Hey Man,

Have you got around to getting those pics on Photobucket yet?

 

Ahhhh you have a convertible on the rack I see.
You are correct, but, the factory FUEL system can handle aprrox 8lbs of boost. Put bigger injectors in there, then even more. Do you want to run 25lbs of boost, then run a 12 injector set up. The fact is that most people won't boost their x-fire over 10 psi(turbo), so the only thing you really need to worry about is the internals, and how much they will hold. If you are willing to start digging into the engine, then chances are you can afford the fuel upgrades needed.
BTW, One of my SRT8 friends who deals dirrectly with deitweiller (sp?) has informed me that they have some DC engineers moonlighting over there, and they may have, or are close, to cracking the code on the SRT8 controllers, and theirs is just like ours.

 

not yet but i will be getting more pics and vids to come

 

good eye

 

I thought about ordering a buch of them and selling them as a mod to us coupe guys, and gals.

 

Nice rear turbo setup!
That is the exact layout that I was thinking about for my car to do a twin charged applicatiion.. What size turbo are you running? I was thinking a GT40 would work good for a rear setup on my car.

 

WOW im really excited to see this in action!!

props!

keep us informed!

 

What do you know max, rear turbo setup like I said.

 

I was wondering when someone would try a rear turbo... It always seemed like the obvious choice to me.
